Cyber criminals set up a fake advert at the top of Google's search results for the retail firm, ahead of one of the biggest shopping days of the year.

Anyone who clicked on the ad was led to a page suggesting that their computers had been infected with malware.

TECH SUPPORT SCAMMERS

Tech support scams use scare tactics to trick you into paying for unnecessary technical support services that supposedly fix contrived device, platform, or software problems.

These scams can use websites to lure you into contacting fake tech support.

When you engage with the scammers, they can offer fake solutions for your problems and ask for payment in the form of a one-time fee or subscription to a purported support service.

The alarm was raised over the scam by CBS news, who reported that, instead of linking to the online store, the convincing ad redirected anyone who clicked on it to a bogus page, purporting to be run by a Windows Support team.

The popup app appears to have been hosted on a Facebook page, hidden in what appears to be a link to a genuine link to Amazon.com.

By hosting the app on a recognised social media platform, rather than their own servers, this may have helped the hackers to avoid detection by Google's automated scam identification software.

The popup encouraged visitors to call a free support line to resolve the problem.

When a reporter from the organisation rang the number listed, a man with a South Asian accent attempted to takeover their system remotely and charge them a one-time fee of $150 (£115).

The mystery crook quickly became annoyed and hung up the phone when confronted with accusations that he was a scammer.

The ad, set up yesterday, has since been removed from Google's AdSense platform.

A spokesman for Google said: 'This was an abuse of our platform.

'We strictly prohibit advertising of illegal activity and have removed these ads and suspended the account.'

Some tech support scam malware may also come in the form of executable files downloaded on your PC, just like malware.

Similarly, when executed, they may display fake error notifications about your computer or software.
